Cement Clinker Quality Control During Clinker Production

During normal production process, the clinker is always calcined in a fixed temperature range. According to the fluctuation of raw meal composition, the calcination temperature of clinker is generally between 1350℃ and 1450℃. If the temperature in the kiln is too low, it is easy to produce underfired clinker.

Clinkerization - Cement Plant Optimization

The process of clinkerization signifies conversion of raw meal into clinker minerals mainly consisting of C4AF (Aluminoferite), C3A (Aluminite), C2S (Belite) and C3S (Alite) phases along with small percentage of free lime CaO, MgO, Alkalies, Sulphates etc.

The contents of f-CaO in the produced clinker would reveal the effects on the burnability of cement raw meal (Huang et al., 2017). The proper content of f-CaO in the standard cement clinker should be less than 1.5 % according to the Chinese standard [GB/T 21372-2008, 2008], [GB/T 21372-2008, 2008] (Portland cement clinker).

Precalciner – Calciner In Cement Plant, Cement Calciner

The preheated cement raw meal (temperature is about 820 ~ 860℃, not exceeding 860℃), a certain amount of fuel, and hot air (kiln tail flue gas or tertiary hot air) are fed into precalciner at the same time. After entering the calciner, the fuel and raw meals are dispersed by high-speed airflow and in a suspension state at about 900℃.

This ensures the raw meal enters the kiln at an approximate temperature of 900°C. The material created at this stage is called clinker, an intermediate product which constitutes the basis for cement.

The true raw meal to clinker factor is given by: 1/ (1 – Loss on ignition of kiln feed). It is normally about 1.55. The major variation from plant to plant arises because of the dust loss from the kiln feed, which varies from kiln to kiln dependent on the collection efficiency of the top stage preheater cyclone.

Clinker quality depends on raw material composition.

Portland cement is the most common type of cement in the world. It is used primarily to make concrete, mortar, and grout. Portland cement manufacturing begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called raw meal, which is then heated to a sintering temperature as high as 1450 °C in a cement kiln.

The effect of fluorapatite in limestones on the mineral

The raw meal of cement clinker with 3.0 wt% P 2 O 5 was compacted to form ф60mm × 10 mm cylinders and was calcined at 1100 °C, 1200 °C, 1300 °C, 1350 °C, 1400 °C and 1450 °C for 30 min. The obtained clinkers were quickly cooled in air at ambient temperature and were ground to pass the 80 μm square hole sieve.

The Influence of Raw Meal Granulometry on the Formation

Subsequently, the grindability of the clinker and the strength of the cement are influenced, especially in the short-term hydration. Change of granulometry and homogeneity of raw meal can greatly optimize the quality and economy of the cement production process.

This ensures the raw meal enters the kiln at an approximate temperature of 900°C. The material created at this stage is called clinker, an intermediate product which constitutes the basis for cement.

Raw meal and clinker silo monitoring In order to keep production going it is necessary to continuously monitor stock levels in the raw meal and clinker silos. As storage vessels come in many shapes and sizes, level monitoring can be a challenge.

The heated raw meal now enters the kiln where the gas temperature exceeds 2000 °C, where it is transformed into a molten mixture inside the rotating kiln. At the temperature of 1450 °C the minerals in the raw meal undergo chemical reaction to form a new compound known as Clinker, which is the pre-curser for the production of cement.

Manufacturing cement requires the following steps: Crushing and storing raw materials such as limestone, clay, sand, shale, fly ash and bauxite; Blending and milling the crushed materials to produce raw meal; Burning the raw meal to produce clinker; Grinding the clinker with gypsum to produce the final product cement

 · Re: clinker factor. The majority of Portland cement clinker manufactured around the world has a lime saturation of between 90 and 100%. This means that c.1.55 tonnes of raw mix are required and c.0.55 tonnes of CO2 are lost due to calcination of the CaCO3 in the raw material. The clinker factor is therefore 0.65 x the amount of raw mix. Reply

Potential of preparing cement clinker by adding the

 · This paper evaluated the potential of preparing cement clinker by adding the sludge into raw meal by a series of experiments. The results revealed 2.0 % addition of the sludge markedly improved the burnability of the produced clinker, and promoted the formation of alite with more amounts and smaller size, but the 5.0 % addition of the sludge .

Quick real-time analysis of raw mix, meal, clinker or cement let cement manufacturers automatically adjust the dosage and mixing of raw materials. The stable targeted material chemistry can be maintained with a low standard deviation of Lime Saturation Factor (LSF), Silica (SR), Alumina (AR) Ratios ensuring good quality cement is made.

Manufacturing Process – Continental Cement

To save energy, modern cement plants preheat the meal before it enters the kiln. Rising more than 350 feet, hot exit gases from the kiln and clinker cooler combined with fuels such as ground coal, petcoke, natural gas, and recycled waste streams, heat the raw materials as they swirl through the cyclones.

Several variables can affect the maintenance of this coating including large fluctuations in raw meal parameters and poorly nodularised clinker can result in liquid phase segregation, the use of high-sulfur fuels, combined with poor combustion engineering and a number of factors that can cause coating to disappear completely.
